a code snippet illustrating how is below. Âthis is not stand-alone, i.e., it will not compile. Âyou must add your own code to:
- set up and execute the file selector itself (here named fileSel),Â
- write the routine registerFile(),Âwhich is responsible for registering the file with your program for subsequent processing, whatever that means to you. Â(typically, a list that, once completely filled (i.e., as returned from file selector), is traversed for individual file processing; though there are certainly other ways to effectuate this.)
- as well, the routine fileType() can be expanded to explicitly include/allow for only certain file types, returning:Â
- FTDIR Â- it's a directory
- FTFILE - it's a file to process
- FTDONOTPROC - it's a file we don't care about, so ignore

No. ÂYou can use GFileEnumerator or GDir to traverse the tree â deciding
how to handle hidden files, symlinks to directories, crossing file
system boundaries, etc. as the definition of âall filesâ depends...
